More bugs fixed for views. (CVS 416) (check-in: 81307762 user: drh tags: trunk)

VIEWs are bound to tables when they are used, not when they are first entered. This works around the problem of what to do if a table is deleted that a view refers to. (CVS 415) (check-in: 6121e5ab user: drh tags: trunk)
03:42
Fix a memory leak in expression processing. (CVS 414) (check-in: dfe431c9 user: drh tags: trunk)
03:11
Additional tests of flattening (CVS 413) (check-in: e1d93c59 user: drh tags: trunk)
03:03
Suppress superfluous OP_OpenTemps when flattening subqueries. (CVS 412) (check-in: 000441c8 user: drh tags: trunk)

Bug fixes and additional tests for the subquery flattener. (CVS 411) (check-in: 2c05389e user: drh tags: trunk)

Pager optimization: do not write or journal free pages. This results in a 2x performance gain for large INSERTs and a 5x performance gain for large DELETEs. (CVS 410) (check-in: cf1ebcfb user: drh tags: trunk)
19:00
Change the btree node balancers to sort nodes into accending order. This improves insert and delete speed by 25%. (CVS 409) (check-in: abbb999d user: drh tags: trunk)
17:04
Subquery flattening is implemented and passes all regression tests. We still need to add addition tests to the suite to further exercise the flattener, however. (CVS 408) (check-in: d5d3e79c user: drh tags: trunk)
